## 打印Hello World！ 在Ruby中 **(**Printing Hello World! In Ruby**)** ##

To print text (Hello World! Or anything else), we use following two methods,

要打印文本(Hello World！或其他)，我们使用以下两种方法，

1.  **puts** : The word "puts" stands for put string. It adds a newline after the string.
    
    **puts** ：“ puts”一词代表放置字符串。 它在字符串后添加换行符。
2.  **print** : The functionality of this method is same as of puts but it does not adds newlines implicitly like puts.
    
    **print** ：此方法的功能与puts相同，但不会像puts那样隐式添加换行符。

**Variables used:** No variables are required as we only have to print the statements. We don't have to store anything.

**使用的变量：**不需要变量，因为我们只需要打印语句。 我们不必存储任何东西。

## Ruby代码打印“ Hello World！” **(**Ruby code to print "Hello World!"**)** ##

=begin 
    Ruby program to print Hello World.
    =end
    
    puts "Hello World!"
    print "Hello World!"
    puts "Hello World!"

**Output**

**输出量**

Hello World!
    Hello World!Hello World!

**Code explanation:**

**代码说明：**

The code illustrates an **example to print a string "Hello World!" in Ruby programming language**. This uses the puts and print methods to print the string and output **"Hello world"** using these methods.

该代码说明了**打印字符串“ Hello World！”**的**示例。** **用Ruby编程语言编写** 。 这使用puts和print方法来打印字符串，并使用这些方法输出**“ Hello world”** 。

You can observe in the output that the print method is not providing a newline and two statements are printing together. Though, both the methods have the same functionality but still use them wisely.

您可以在输出中观察到print方法未提供换行符，并且两个语句一起打印。 尽管这两种方法都具有相同的功能，但是仍然明智地使用它们。
